Reverse smil animation based on path - animation

I'm new to SVG and trying to reverse run the animation instead of starting it from the beginning. Is there a way to do it using SMIL or should I just switch to keyframes?

Thanks for all help in advance!


You may use the values attribute instead of to like this:
The red path is what you have, the blue one is using 3 values
I hope this is what you are asking.

I need the arrow (class = "arrow") itself to move along long lines and draw it.

Advise which library I can use

You could do this using svg smil animations:
A Guide to SVG Animations (SMIL)
Your arrow animations could be achieved by
<animateMotion> for moving the arrow element and
animating the stroke-dashoffset property.
Animated example
svg {
border: 1px solid #ccc;
width: 33%;
overflow: visible;
display: block;
}
path {
stroke-width: 10;
stroke: #000;
}
<p>Click on animation for replay</p>

Quite likely, you will have to tweak your svg viewBox to get the desired result.
A common trick is to position element that's supposed to move along the motion path to x/y = 0.

How to reverse animate motion?

Why my animation doesn't start from the top to the bottom ? How to reverse it correctly ? I don't know what I should change. (I tried keyPoints="1;0" keyTimes="0;1" which didn't work)
<svg xmlns="http://www.w3.org/2000/svg" width="500" height="350" viewBox="0 0 500 350"><path d="M404.88 470.22V79.69c-.2-19-14.21-33-17.52-36.19s-16.77-15.19-34.7-15.45h-1.11c-28.65.35-59.55-.12-319.52 0H28" stroke="#000" stroke-miterlimit="10" fill="none" id="motionPath"></path><rect id="circle" x="-25" y="-25" rx="15" ry="15" width="50" height="50"></rect><animateMotion xlink:href="#circle" from="50" to="450" dur="5s" begin="0s" repeatCount="1" rotate="auto" fill="freeze"><mpath xlink:href="#motionPath"></mpath></animateMotion></svg>

It is necessary to remove from =" 50 " to =" 450 " since the length of the path of movement is determined by the length of the path mpath
The direction of movement of an object along a path depends on two parameters
keyPoints="1;0" - movement from start to finish
keyTimes="0;1"
keyPoints="0;1" - movement from end to start
keyTimes="0;1"
In the example below, JS is used only to handle the event of pressing the control buttons: forward and back
var animation1 = document.getElementById("forward")
function forwardSVG(){
animation1.beginElement();
}
var animation2 = document.getElementById("back")
function backSVG(){
animation2.beginElement();
}
<div id="pathContainer4">
<button id="btn1" onclick="forwardSVG()">forward</button />
<button id="btn2" onclick="backSVG()">Back</button />
</div>
<svg xmlns="http://www.w3.org/2000/svg" width="500" height="350" viewBox="50 0 500 350">

<!-- Forward motion animation -->
<animateMotion id="forward"

dur="5s"
begin="indefinite"
rotate="auto"
fill="freeze"
repeatCount="1"
keyPoints="1;0"

</svg>

Here is the reverse you want.
I modified the shape a little but you can modify it back again.
Hope that this is the solution to your problem.
you can make it freeze too if you want.

Animating a defined path's d attribute doesn't work on firefox

I'm animating a d attribute of a path that is wrapped around a defs tag and linked using a
few use tags. This works fine on Chrome, however no animation on Firefox. I tried this with relative and absolute paths to no avail.
<svg viewBox="0 0 300 100">
<defs>
<path id="a" d="M0,20 H200 V70 H0z" />
</defs>
<use xlink:href="#a" />
<animate xlink:href="#a" attributeName="d" values="M0,20 H200 V70 H0z; M0,20 H200 V45 H0z" keyTimes="0;1" dur="1s" begin="0s" fill="freeze" />
</svg>
Is the only way to make this work is by repeating the path and animating them all or is there a way to make this work on Firefox?

As commented by #Robert Longson
I think you'd need to repeat the paths. At the moment SMIL changes to
the things that a element points to do not trigger the to
re-render.
Therefore, it is necessary to transfer the animation directly inside the <path> tags
<svg viewBox="0 0 300 100">
<defs>
<path id="a" d="M0,20 H200 V70 H0z" >
<animate
attributeName="d"
values="
M0,20 H200 V70 H0z;
M0,20 H200 V45 H0z"
keyTimes="0;1"
dur="1s"
begin="0s"
fill="freeze" />
</path>
</defs>
<use xlink:href="#a" />
</svg>
Start animation after click

RxJS loading indicator on any ajax request

I need to show a loading indicator any time an ajax request occurs. Based on this question RxJs How to set default request headers? I believe I'll have to create an ajax wrapper to use.
My requirements are to start the loading indicator when a request occurs. It can start again if there is already a request running. When a request completes/errors, I need the loading to go away. It should only go away if all requests have completed though.
In axios I just use interceptors and have a counter. It's pretty simple. I really have no clue how to handle this with RxJS though. My guess would be it needs to do something similar, I just really don't know how to write it.

Build a custom HTTP client that exposes a loading BehaviorSubject. Every time a connection is opened increment the count and decrement the count each time a connection finishes. Have your loading indicator show when the connection count is greater than 0 and hide when it is 0.
class HttpClient {
constructor() {
this.connectionCount$ = new rxjs.BehaviorSubject(0);
this.loading$ = new rxjs.BehaviorSubject(false);
}
incrementConnectionCount() {
this.connectionCount$.next(this.connectionCount$.getValue() + 1);
if (this.connectionCount$.getValue() === 1) {
this.loading$.next(true);
}
}
decrementConnectionCount() {
this.connectionCount$.next(this.connectionCount$.getValue() - 1);
if (this.connectionCount$.getValue() === 0) {
this.loading$.next(false);
}
}
get(url) {
this.incrementConnectionCount();
setTimeout(() => { // Simulate a http call that takes 2 seconds
this.decrementConnectionCount();
}, 2000);
}
// Do the same for the other verbs, put, post, delete etc
}
const httpClient = new HttpClient();
// Anywhere you want a loading spinner subscribe to the loading observable and show and hide the spinner
httpClient.loading$.subscribe(loading => {
document.getElementById('loading').style.display = loading ? 'block' : 'none';
});
// Show the connection count
httpClient.connectionCount$.subscribe(connectionCount => {
document.getElementById('connectionCount').innerText = connectionCount;
});
// Each time you click the button you will simulate a http get that takes two seconds, press it multople times and it will show for 2 seconds after the last click
document.getElementById('load').addEventListener('click', () => {
httpClient.get('someUrl');
});

SVG - animate opacity

could you please help me out, how to create SVG animation, which will behave like this? https://framer.cloud/aSUDY/
I did my best, but it always misbehaves :-(
Here is my code, where I used 6 animations to cycle through (3 to animate from 0.5 to 1 opacity and three to animate vice versa)

I've changed the animations to use values, they don't really need to be linked.
I've removed the duplication and the elements that really were'nt doing anything other than add complexity.
